Hydroxylated derivatives were designed and synthesized based on the information of oxidative metabolites. Compounds derived from β-substituted (2R,3R)-2-amino-3-hydroxypropionic acid showed improved inhibitory activities against the binding of MIP-1α to h

Based on the original spirodiketopiperazine design framework, further optimization of an orally available CCR5 antagonist was undertaken. Structural hybridization of the hydroxylated analog 4 derived from one of the oxidative metabolites and the new orally available non-hydroxylated benzoic acid analog 5 resulted in another potent orally available CCR5 antagonist 6a as a clinical candidate. Full details of a structure-activity relationship (SAR) study and ADME properties are presented.
